Application nled Januaryl?, 1913. Serial No. 742,604.

State of Connecticut, have invented certain new and useful Improvements in Combination Organ Stop-Actions, of which the following is a specification. n

This invention relates to combination organ stop actions, the object of the invention being to `provide means ofthe character 1ndicatedI by which various combinations of stops can be operated and whereby the combinations can be readilyand quickly made to conform to theparticular music to be played. v

In the drawings accompanying and forming part of the present specification I have shown in detail one of the several forms of embodiment of the invention, which to en-.

A may depart radically therefrom in several respects within the scope of the invention defined by said claims.

Referring to said drawings: Figure 1 is a diagrammatic view in perspective of stop operating mechanism involving my invention. Figs. 2 to 5 inclusive are detail views in sectional elevation of portion of a trace, an actuator thereon and a roller, the' parts being shown in different positions by full and dotted lines. Fig. 6 is a view inelevation of part of'a trace with several of the .actuators thereon. Fig. 7 is a longitudinal section on the line 7 7 of Fig. 6. F ig. 8 -is a detail view of a stop key, controlling spring therefor and certain coperating parts. Fig. 9 is a detail view showing a dismountable or removable actuator. Fig. 10 is a similar view of an actuator which will be hereinafter morel particularly described.

Like charactersA refer to likeparts throughout the several figures `of the drawings, which it will be perceived are on different scales. i

A pipe organ comprises as is well-known a number of stops, and various means may be provided for independently or individually operating the same. I do not show the stops but I do illustrate several stop-keys denoted by 2. It will be evident that the stops may be primarily operated by other means, the keys constituting one common device for securing this particular function. The stop-keys 2`are supported for independent rocking motion or oscillation by the relatively-stationary shaft 3 as customary in this art. Between each stop key and the coperative stop is arranged mechanism by which when the stop key is depressed, the stop 'governed therebywill be operated. This mechanism may vary greatly as to character; that shown involves in its make-u what is known as a roller 4. The ro 1ers 4 as represented, consist of skeleton or open rockers of approximately rectangular form, the end cross bars of which are provided with outwardly extending pivots 5 projecting through openings in .the parallel bearings or strips 6 mounted on and rising from the board 7. The forward pivots 5 have crank portions 8 connected respectively by links 9 with the rearpart. of the bodies of the keys 2. It will, therefore, be clear that when the finger portion of a key 2 is depressed and then elevated, the roller 4 associated therewith will be given full oscillation. When a stop key 2 isv off, the roller or skeleton rocker 4 connected therewith will occupy the position shown for example in Figs. v3 and 5. When, however, said stop key is on the roller or rocker will be in the position shown in Figs. 2 and 4, so that the stop connected therewith will be operated. A spring 2 acts against each stop key to hold the same up or ofi or down or up. The connections between the respective rollers and stops are not shown, as they are quite common. Each stop key and roller coperative therewith' has inoperative and operative positions.k -When the finger portions of the stop keys are up, this signifies that said stop keys are'of or 1n their inoperative positions, the rollers or rockers being' in the position shown in Figs. 3 and 5. however, are represented as in Figs. 2 and 4, they are in their operative or effective positions, the-stops associated therewith be ing operated at this time.

The stop keys 2 to which I have referred have been considered as main stop-operating devices for the reason that the stops can be initially ory primarily actuated through them When the rollers,

and also for the further reason that there are other stop-operating devices which can be considered auxiliary in their character, in that they are subordinate in a measure to the primary stop-operating devices. The auxiliary stop operating dev ices are provided to operate, through the aid 'of suitable mechanism, stops in combinations, and the invention turns on this particular feature. There have been heretofore provided means by which this result can be obtained, but the prior means have been complicated and require unusual time to effect changes in combinations. The auxiliary stop-operating devices may like the main ones Vary decidedly as to nature, the manually-operable pistons 10 yanswering satisfactorily in this respect, their front ends having knobs or buttons 11 to facilitate their action. To the rear ends of the pistons 10 are connected arms 12 fastened to rock-shafts 13, in turn carrying rock-arms 14 to which are pivoted links 15 connected to arms 16 supported for independent rocking motion by the fixed or stationary shaft 17. The pistons 10 are normally held in their forward or off positions by suitable means, the pull springs 17 connected with the respective arms 16 serving properly in this connection. To the upper ends of the respective arms 16 are connected strips 18 or as they are known in the organ art traces. In the organization shown these traces have means connected therewith for operating the rollers or rockers 4 preferably but not essentially, either to move the same to operative or inoperative positions depending upon the position of the said means. The means shown for operating the respective rollers 4 consist of actuators each denoted in a general way by 19 on the respective traces or strips 18 each actuator as will hereinafter appear, having two portions, one for moving a roller toward an inoperative position if required, and the other for moving said roller toward its operative position if necessary on the advancing movement of the trace carrying said actuator. The actuators may vary considerably as to construction, although I will describe those shown. Each actuator has a shank 20, and a segmental head or active portion 21, said shank being pivoted between its ends as at 22 to its appropriate trace 18. When the lower branch of a head 21 extends below the lower edge of the trace supporting the same, said head when said trace is advanced, will shift the roller 4 next the same from operative to inoperative position if necessary, while if the upper branch of said head be above the upper edge of the trace, said head on the advance of the trace, will move the roller from inoperative to operative position if necessary. These actuators 19 are preferably made from sheet metal in order to secure a certain amount of resiliency which is advantageously utilized for holding the same in the respective positions by various means and to also aid in shifting the saine. The heads of the pivots 22 as shown best in Fig. 7 are rounded, and these rounded Aheads are adapted to engage alternately1 in cavities as 23 in the adjacent overlapping heads for holding said adjacent actuators in their two shifted positions in a certain manner as shown best in Fig. 7. It will be clear that the actuators on each trace are in overlapping relation, and they are deflected slightly outward between their centers of motion and heads as shown. It will be evident that any stop-key 2 can be manually operated to put into action and then out of action the stop associated therewith.' Stops in combinations are operated through the agency of the pistons 10 as will hereinafter appear.

Reference may be had to Fig. 1 wherein all the stop-keys 2 are oft', said stop keys and the rollers respectively connected therewith being, therefore, in their inoperative positions, the result being that the cooperating stops are in inactive relations. All the pistons 10 are also in their off positions due to the arms 16 being held back by the springs 18 as already set forth. In this Fig. 1 it will be clear that if the first piston 10 be put on or moved inward, the trace 18 connected therewith will be moved to the right and on such motion the lower portion of the head 21 of the first actuator, will strike the lower longitudinal side bar of the first roller 4 and will swing said roller 4 to operative position and hence cause the action of the stop connected therewith. On such movement of said first trace 18 the upper portion of the head of the second actuator is shown as up, so that this head as said first trace 18 moves toward the right in said Fig. 1, will not have any effect on the second roller. r1`he second actuator 19, however, on the second trace is in position to shift the second roller andi necessarily t-he stop connected therewith into operative position. The actuators are, therefore, shown as occupying different positions in said Fig. 1.

In Figs. 2 to 5 inclusive a single trace provided with a single actuator and a co-,

operating roller are shown, and these views illustrate the action of the parts. In Fig. 2 the trace 18 is at the left of its movement, the upper portion of the head 21 of the actuator 19 being above the upper edge of the trace and the roller 4 being in operative position as shown by full lines. When the trace 18 in said Fig. 2 is advanced or moved to the right, the upper portion of the actuator 19 will by engaging the upper longitudinal bar .of the rocker swing said rocker to the position shown by dotted lines and as soon asthe trace is released said trace will be returned to its original position by the lll sprin 18 connected therewith. In Fig. 3 the ro er iS shown as being in an inoperative position, While the actuator therein is shown as being in the position it would occupy to move said roller from an inoperative to an operative position, this View being intended to bring out the fact .that the t-race with the particular actuator thereon can be reciprocated without affecting the roller.

Figs. 4 and 5 illustrate one way of set-ting the actuator. In Fig. 4 the roller is shown as being in an operative positionand the actuator is shown with the upper portion .of its head above the trace or that it would occupy to effect the movement of said roller from an inoperative to an operative position. To reverse this condition the following procedure may be adopted: The stop kev connected with said'roller will be held down and the trace 18 through the action of its appropriate plunger will be moved to the rlght, and said roller being thus held immovable will swing said actuator 19 on its center and move the same from-the dotted to the full line position. In Fig. 5 the opposite showing is made, the upper portion of the head of said actuator being above the top edge of the trace and the roller 4 being in its inoperative position to which, for eX- ample it may have been moved by the trace 18 as the same is moved to the right. To shift the actuators 19 from the full line position in Fig. 5V to the dot-ted line posit-ion the proper sto-p key 2 will be held. off and said trace will be moved to the right, and on this movement the upper side bar of the roller 4 will engage the upper portion of the actuator and will swing said actuator to the dotted line position. l

In Fig. 1 all'the stop keys are up or off while all the pistons 10 Iare also off or out. In the organization shown I prefer to secure the combinations by the inward movement of the pistons. For example it will be supposed that I wish to-effect the action of a combination of stops governed bythe first three stop keys shown, through the action of the 'secondpistonlL In this case I would first depress said three keys and afterward thrust inthe second piston. When the three stop keys are depressed or put on the rollers 4 connected.therewith are brought to the position shown in Figs. 2 and 4, so that when the second" trace 18 -is moved to the right in Fig. 1 the upwardly extending portions of the first, secondand third actuators 19 strike the upper cross" barsv of the adjacent and cooperating rollers and cause the upper portions of saidgactuators to move below the upper edge'ofsaid trace and the lower portions of' said actuators to move below the lower edge oflsaid trace'. The three stop keys can then be elevated to put the rollers connected therewith inoperative positions. In view, therefore, of* this particular condition it will be clear that when the second piston 10 is thrust inward or put on, the first three rollers 4 will be moved from inoperative to operative positions to effect the action of the respective stops connected therewith'. It will be understood that should any actuator be in position to move a roller from operative to inoperative position or vice versa and the roller should already be in such position, the actuator coperative therewith will in this event do nothing in view of the fact that the particular stop is in the relation that it should be. y

In some cases it may be necessary to dis- 'mount the actuators 19 andV in Fig. 9 I have shown such a construction where this is possible, the' actuator therein shown being denoted by 19 and the pivot therefor by 20.\

In the edge of the shank of said actuator is an open slot 25 to receive said pivot 20. This is one of the several simple ways of removabl supporting the actuators.

The actuators as I have termed them wherever they appear in Figs. l to 9 inclusive are shown diagrammatically and draftsmans license has been adopted somewhat in these particular views. In Fig. 10, however, where one of the actuators is shown separated from everything else, I have shown the outlines of said part precisely and exactly as I use it in an organ.
